Iitafile zeNadcc zonyango lweSater
Intshayelelo
I-Nadcc, ekwabizwa ngokuba yi-sodium dichloroisory, yindlela ye-chlorine esetyenziselwa ukubulala iintsholongwane. Ihlala isetyenziselwa ukuphatha inani elikhulu lamanzi kwiimeko zikaxakeka, kodwa inokusetyenziselwa unyango lwamanzi lwasekhaya. Iitafile ziyafumaneka kunye ne-NADCC eyahlukeneyo yokujongana nemiqulu yamanzi ahlukeneyo ngexesha elinye. Bahlala beyinyibilikisa kwangoko - ngamacwecwe amancinci anyibilikisa ngaphantsi komzuzu.
Inceda njani ukungcola?
Xa iyongezwa kumanzi, amacwecwe e-nadcc ekhupha i-hypoctlorororororororororororororororororororororouse acid, enika i-microorganisms nge-oxidation kwaye kubulala. Izinto ezintathu zenzeka xa i-chlorine yongezwa emanzini:
Ezinye i-chlorine ziphikisana nezinto eziphilayo kunye neebhajethi emanzini nge-oxidation kwaye zibulale. Eli candelo libizwa ngokuba kutsho kwi-chlorine.
Ezinye i-chlorine i-chines kunye nenye into ephilayo, i-ammonia, kunye nentsimbi yokwenza i-chlorine entsha. Oku kubizwa ngokuba yi-chlorine.
I-chlorine egqithisileyo ihlala emanzini engapheliyo okanye engaphili. Eli nxalenye libizwa ngokuba yi-chlorine yasimahla (FC). I-FC yeyona ndlela isebenzayo ye-chlorine ukuze ichize intsholongwane (ngakumbi iintsholongwane) kwaye inceda ukukhusela u-retamamition wamanzi aphathwayo.
Imveliso nganye kufuneka ibe nemiyalelo yayo yedosi efanelekileyo. Ngokubanzi, abasebenzisi balandela imiyalelo yemveliso ukongeza amacwecwe achanekileyo ubungakanani benani lamanzi ukuba anyangwe. Amanzi akhuthazwe kwaye ashiywe ixesha elibonisiweyo, ihlala imizuzu engama-30 (ixesha lokunxibelelana). Emva koko, amanzi abulala iintsholongwane kwaye alungele ukusetyenziswa.
Ukusebenza ngempumelelo kwe-chlorine kuchatshazelwa yi-turbidity, into ephilayo, i-amonia, ubushushu kunye nePH. Amanzi anamafu kufuneka acotywe okanye avumeleke ukuba ahlawulwe ngaphambi kongeza i-chlorine. Ezi nkqubo ziya kususa amasuntswana anqunyanyisiweyo kwaye aphucule impendulo phakathi kwe-chlorine kunye ne-pathogens.
Imithombo yeemfuno zamanzi
I-turbidity ephantsi
I-5.5 kunye ne-7.5; Intsholongwane ingenakuthembeka ngaphezulu kwe-PH 9
Isondlo
Iimveliso kufuneka zikhuselwe kubushushu obukhulu okanye ubushushu obuphezulu
Iitafile kufuneka zigcinwe kude nabantwana
Ixabiso le-dosage
Iitafile ziyafumaneka kunye ne-NADCC eyahlukeneyo yokujongana nemiqulu yamanzi ahlukeneyo ngexesha elinye. Singayenza ngokwezifiso ngokweemfuno zakho
Ixesha lokunyanga
Ingcebiso: Imizuzu engama-30
Ubuncinci ixesha lokunxibelelana luxhomekeke kwizinto ezinje nge-pH kunye nobushushu.
